all connected ports and use numbers. The netstat command displays network connection, route table, and network interface information, allowing you to know which network connections are in operation. If no parameter is included during use, netstat displays active TCP connections. The common format of this command is: Netstat [-a] [-e] [-n] [-o] [-p Protocol] [-r] [-s] [Interval] Output Information After netstat is executed, the output result is Active Internet connections (w/o servers)Proto Recv

. The logon process includes entering a valid password and personal account, and then submitting it to the system for verification. The logon system can be divided into four non-overlapping states: Getting SSN, Getting PIN, Validating, and Rejecting. Each status has a complete set of transfer transitions to determine the sequence of States. The status is represented by a rounded rectangle. The transfer is represented by a line with arrows. The event

analysis and design of Kathy Sierra.Although the actual case is the best way to learn the principles or patterns of design, but through the introduction of this article, no contact with these principles or the learning phase of the Java programmer can also understand the 10 object-oriented design principles. In fact, every principle requires a lot of space to be clear, but I will try to be concise. 　　 principle 1:dry (Don ' t repeat yourself)That is, instead of writing repetitive code, use the

(principles). Dry–don ' t Repeat yourself Our first object-oriented design principle is: DRY, from the name you can see that DRY (don ' t repeat yourself) means not to write duplicate code, but to abstract it into reusable blocks of code. If you have two or more blocks of the same code, consider abstracting them into a single method, or you use hard-coded values several times, set them as public constants. The advantages of this object-oriented design principle are ease of maintenance. It is im

functionality. This means that even if you use common code to validate OrderID and SSN, they will not be the same. The use of common code to implement two different functions, in fact, is to approximate the two of these features are always bundled together, if OrderID changed its format, SSN verification code will be interrupted. Therefore, use this combination with caution, and do not arbitrarily bundle s

value combination in the indexed column is unique. For example, if you create a unique index full_name on a combination of last_name, first_name, and middle_initial columns, no two people in that table can have the same full name.Both clustered and nonclustered indexes can be unique. Therefore, as long as the data in the column is unique, you can create a unique clustered index and multiple unique nonclustered indexes on the same table.Specifying a unique index makes sense only when uniqueness
